Abstract: In a method for detecting power usages of an electronic device, parameters of components of the electronic device and a power usage of the electronic device are obtained within a predetermined Nth period. The electronic device determines if the power usage of the electronic device is normal according to the parameters of components of the electronic device within the Nth period. The electronic device records information of applications which run in the electronic device within the Nth period when the power usage of the electronic device is abnormal.

Abstract: Provided is a method of detecting abnormal power consumption of an electrical device during a standby time period. The electrical device includes an operating system. The method includes: obtaining a first system log of the operating system at a first time point; obtaining a second system log of the operating system at a second time point; determining whether the electrical device is in a standby mode from the first time point to the second time point by comparing the first system log with the second system log; if the electrical device is in the standby mode, determining whether the operating system is in a sleep mode; if the operating system is not in the sleep mode, analysing the system log of the operating system from the first time period to the second time period, so as to obtain and store an abnormal power consumption information.

Abstract: A computing device establishes communication between a first electronic device and a second electronic device for transmitting data. The computing device receives first register information from the first electronic device and second register information from the second electronic device and saves the first and second register information into a route list. The computing device sends the second register information in the route list to the first electronic device when receiving commands from the first electronic device, so that the first electronic device directly transfers data to the second electronic device according to the second register information.
